CENTRAL-PIVOT GUN CARRIAGE.

Application filed July 3,

To all whom t may concern.'

Be it known that I, EUGNE SCHNEIDER, a citizen of the Republic of France, resident yoit Paris, France, have invented new and usetul Improvements in and Relating to Central-Pivot Gun Carriages, which is fully set torth in the following speciication.

This invention has for its object to provide an improved central pivot gun carriage im with mechanisms or'etecting transverse and longitudinal adjustments of the foot-step bearing.

An embodiment of this invention is illustrated-by way of example' in the accompanying drawings in which:

Figure l is a longitudinal sectional elevation of the improved gun carriage taken along the axial plane of the mechanism for eiecting the longitudinal adjustment of the toot-step bearing.

Figure 2 is a' partial cross section taken along the line'2'-2 of Figure l.

Figure 3 is a partial elevation in section taken along the line 3--3 of Figure l of a detail, and

Figure 4 is a horizontal section taken along the line A41: of Figure l.

The improved gun carriage comprises vin the known mianner a hollow pedestal A in which the foot-step bearing B, wherein turns the pivot pin C supporting the gun` cradle D, is capable of being adjusted in two directions at right angles to each other.

According to this invention the central pivot C is connected by means of a ball and socket joint c to al slide-block E guided in an arm F fixed to a platform G which is movable around the pedestal A and on which the gun servers take their places. Easy running of the platform may be assuredV by means of rollers g working in a rolling track a formed on the pedestal.

he main characteristic feature of this invention is the mounting, upon the pedestal A, oit' two hand-wheels H and I that are capable of rotating freely around the said pedestal, and serve :tor operating respectively the two mechanisms for adjusting the tootstep bearing B of the central pivot C.

In the illustrated example, each ott these hand-wheels is fixed to a ring of teeth (It and z' respectively) resting on a supporting ledge (al and (L2 respectively) formed on the pedestal A. The ring of teeth It meshes with the pinion J, the axle pin j et which 1923. Serial Eo. 649,306.

revolves in the pedestal and is connected in a known manner by means of a transmission gearing J1-J2J 3-J 4, to a screw J5 pivoted to an axial pin b carried by the foot B1 of the foot-step bearing B. This foot is likewise in a known manner movable in a guide b2 of a slide-block B2 which is movable in a direction at right angles to the axial plane of the slide-way b2 in a guide A1 formed in a part that is liked to a stationary part such as the bedplate A2 for the pedestal. The ring teeth e', Xed to the operating hand-wheel I, mesh with a pinion K (the axle pin lo of which is journalled in the pedestal A) connected by transmission gearing Kl-Kz-KS-K to a screw K5 pivoted at b1 to the slide-block B2. As will be perceived, the ball and socket joint o allows a permanent connection between the slideblock E (movable in the arm F) and the central pivot C, whatever may be the longitudinal and transverse inclinations of the latter, so that the platform G will always be carried round irrespectively of the training position. @n the other hand, whatever may be the position he occupies relatively to the pedestal A and to the mechanisms for efecting the adjustment, the gun server charged with operating the said mechanisms,

will always find withinhis immediate reach, one point of the control hand-wheels (H, I) for actuating` the said mechanisms.

It is to be understood that the mode of mounting the control. hand-wheels around the pedestal `may be varied at will. For instance these hand-wheels, for the sake of greater mobility, may be 'formed on the outer ring or race of a ball bearing, the inner ring or race of which is carried by the pedestal.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is l. A gun carriage comprising a pedestal, a gun pivot pin having a foot-step bearing adjustable in two directions at rightangles to each other, a gun servers platform movable around the pedestal and having an arm extending therefrom, a block slidably mounted on said arm, a ball and socket joint between said block and the gun pivot pin, and a pair ot hand wheels movable around said pedestal and having ring gears thereon meshing with the actuating gears of the foot-step bearing adjusting mechanism, said hand-Wheels providing for adjust-ment of the foot-step bearing by the gun server from his position on the platform regardless of the. direction of guii-fre- 2. A gun'carri'age comprising'apedestal,'

a 0un ivot ain having an ad'ustable footstep bearing, a platform movable around;

said pedestal, and a universal connection between said platform and the gun pivot pin. Y'

3. A gun Vcarriage comprising `a' pedestal, a gun pivot pin having an adjustable'foot-- step bearing, mechanism-for adjusting saidV foot ystep bearing, and a hand Wheel movable around the pedestal and geared With said ladjusting mechanism.'-

4. A gun carriage comprising `a pedestal, a gun mounting pivoted on said pedestal, a platform movable around 'said pedestal, and means for moving said platform around the pedestal'by aY turning movement of the gun, said meansv comprising auniversal con-V nection between' the gunmounting an'dfthe platform".l i

5. In combination', apedestal,l a'gun pivot` ally-mounted on said pedestal and having an adjustable foot-step bearing", mechanism for adjusting' saidY bearing in diifereiit directions, and means encircling said pedestal for actuating` said adjusting mechanismV 'foi-iii' 'and the gun mounting',

step bearing, mechanism for adjusting said bearing, a gun servers platform mounted on said pedestal to rotate around the same, a universal connection between said platand a 'hand' Wheel mounted on said pedestal to rotate around the same, said hand Wheel being geared With said adjusting mechanism 'whereby the latter may be actuated from different positions around said pedestal.

8. In combination, a pedestal, a gun mounting having' an adjustable' foot step bearing, a plurality of mechanisms for adjusting said bearing'insdi'fferent directions, anda pluralityof devices rotatable around said pedestal for actuating 'said' adjusting 'mechanisms from"aiiy position around the pedestal.

In combination, a pedestal, Ya gunV mounting pivoted on said pedestalfand hav# 'ing an adjustable' foot 'step"bearing, 'gear operated mechanism 'for adjusting said bearing in' different' directions, a gun servers platform rotatable around said pedestal by 'a turning movement of the gun mouiiting,`

and-a pair of'hand Wheels rotatable` around said pedestal and provided with ring gearsV meshing with the actuating gears of said adjusting mechanism. Y
